动画汉堡导航

Question

我正在为我的网站创建一个完整的页面导航阴影，以便在所有设备上都相同。目前我有两个按钮，一个用于当阴影在视野中时，另一个用于不在视野中时。我想知道是否最好始终存在一个按钮以便可以对其进行动画处理？我的目标是像这里的squeeze动画这样的东西，但我不确定如何在两个按钮上制作动画而不是只有一个按钮 - 或者你如何从头开始创建它。

这是我正在使用的内容;

const navButtons = document.querySelectorAll('button.nav-action');
const siteNav = document.querySelector('.site-nav');
function onClick(event) {
siteNav.classList.toggle('active');
}
navButtons.forEach(button => button.addEventListener('click', onClick));

.site-header {
height: 80px;
background-color: #FFFFFF;
display: inline-flex;
position: fixed;
top: 0;
left: 0;
right: 0;
z-index: 1;
box-shadow: 0px 0.5px 10px #000000;
}
.site-header-fill {
height: 80px;
}
.site-logo-container {
height: 60px;
margin-left: 20px;
margin-right: auto;
margin-top: 10px;
margin-bottom: 10px;
display: block;
float: left;
}
.site-logo {
height: 60px;
width: auto;
float: left;
}
.site-nav-action-container {
height: 50px;
width: 50px;
max-width: 50px;
margin-left: 10px;
margin-right: 10px;
margin-top: 15px;
margin-bottom: 15px;
display: block;
float: right;
text-align: right;
}
.site-nav {
	height: 100%;
	left: 0px;
	position: fixed;
	top: 0px;
	width: 100%;
	background: #3399ff;
	z-index: 2;
	display: none;
}
.site-nav.active {
display: block;
}
.site-nav-content {
	width: 20%;
	position: absolute;
	left: 50%;
	top: 50%;
	-webkit-transform: translate(-50%, -50%);
	transform: translate(-50%, -50%);
}
@media only screen and (max-width: 500px) {
.site-nav-content {
width: auto;
position: absolute;
left: 50%;
top: 50%;
-webkit-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
}
}
.site-nav-pages {
text-align:center;
}
.nav-action {
height: 50px;
width: 50px;
}

<div class="site-header ">
<div class="site-logo-container">
<img class="site-logo" src="https://via.placeholder.com/1000x300" alt="Logo">
</div>
<div class="site-nav-action-container">
<button class="nav-action">
<p>☰</p>
</button>
</div>
</div>
<div class="site-nav">
<div class="site-nav-action-container">
<button class="nav-action">
<p>×</p>
</button>
</div>
<div class="site-nav-content">
<div class="site-nav-pages">
<p>Page 1</p>
<p>Page 2</p>
<p>Page 3</p>
<p>Page 4</p>
<p>Page 5</p>
</div>
</div>
</div>

目前，阴影现在的功能是基于按下的按钮可见或不可见，但我想知道是否有一个按钮是要走的路，或者将图标放在按钮外面是否效果最好。

理想情况下，汉堡包会在从顶部显示阴影时制作动画，但一旦对按钮的合理方法进行了排序，我就会解决这个问题。任何帮助将不胜感激，因为我显然不知道我在这里做什么。

提前谢谢。

您可以使用 to ☰ ×效果。您可以自己编写所有行标签。 第一个代码片段是我经常使用的动画，第二个是我认为你想要的动画。我安装了两者，因此您可以使用任何您想使用的内容。

const navButtons = document.querySelectorAll('button.nav-action');
const siteNav = document.querySelector('.site-nav');
function onClick(event) {
siteNav.classList.toggle('active');
}
navButtons.forEach(button => button.addEventListener('click', onClick));
const menuIcon = document.querySelector(".menu-icon");
menuIcon.addEventListener("click", () => {
menuIcon.classList.toggle("toggle")
siteNav.classList.toggle('active');
})
